Claims.

Our invention relates to cartons and has for an object to provide a carton adapted tov be used for packaging liquid substances adapted to solidify and has for an object to provide a carton from which the solidified substances may be readily removed or dispensed.

An object of the invention resides in constructing the carton with a tray havinga bottom and lateral walls hingedly connected therewith, said lateral walls being disconnected at their adjoining edges to permit swinging of the walls from collapsed position in which the tray forms a cutting board to erected position in which the contents are enclosed.

Another object of the invention resides in providing a hoop encircling said lateral walls and formed with lateral walls adapted to lie adjacent the lateral walls of the tray, said hoop holding the lateral walls of the tray in erected position and being readily removable from said tray to free the lateral walls of the tray, to permit of swingingof the same to collapsed position to expose the contents of the tray.

A still further object of the invention resides in providing a cover for the carton adapted to fit over said hoop and to cover the contents of the tray.

A feature of the invention resides in providing means for securing the hoop to the cover so as to cause the hoop to become disengaged from the tray when the cover is removed from the tray.

' Another object of the invention resides in providing stifiening means for reinforcing the upper edges of certain of the walls of either of the tray or the hoop to prevent bulging of the walls when the containerwithin the tray is filled with the liquid substance to be packaged.

Another object of the invention resides in constructing two of the walls of the tray double with flanges therebetween, arranged to fold into overlying planiform position, when collapsed, and to fold into extended position when erected to stiffen and reinforce the walls of the tray.

A still further object of the invention resides in providing locking tongues on certain of the walls of either of the cover or hoop and in constructing corresponding locking shoulders on the adjoining walls of the other thereof to secure the hoop to the cover when the cover is applied to the assembled hoop and tray whereby the tray is caused to be removed from the hoop when access to the contents of the tray is desired.

Other objects of the invention reside in the novel combination and arrangement of parts and in the details of construction hereinafter illus- I invention shown in collapsed position.

In the packaging and dispensing of cheese and similar substances which are poured in a liquid state in a container to be subsequently removed therefrom after solidification, considerable difficulty has been encountered in that the container expands when the cheese is poured in the same thereby causing the package to have a deformed appearance. At the same time considerable inconvenience has been encountered in dispensing the cheese from the package. The present invention provides a simple and convenient carton whereby dispensing and packaging of cheese is greatly simplified.

Our invention comprises a tray A, best shown in Figs. 4 and 9; a hoop B shown in detail in Fig. 7, and a cover C illustrated in Fig. 3. These parts cooperate in a manner to perform the deblank is formed with a number of transverse scores l2, [3, I4, l5, l6, l1, l8 and I9. These scores divide the blank into a bottom 2|, side walls 22 and 23 hingedly connected thereto, flanges 24 and 25 hingedly connected to the side walls 22 and 23, auxiliary walls 26 and 21 hing-.

edly connected to the flanges 24 and 25, and flaps 28 and 29 connected to the auxiliary walls 26 and 21. The blank isnotched .at the corners to form end walls 3| and 32 which are hingedly the scores l3 and I8 and the adhesive of the flaps 28 and-29 caused to adhere to the bottom 2|. The blank is now completed .and ready for use. From Fig. 5 it will be apparent that the score I2 is off-set from the score IS a distance substantially equal to the width of the flange 24. Similarly the score I6 is off-set from the score I9 a distance equal to the width of the fiange 25. By means of this construction the wall 22 is adapted to become spaced from the auxiliary 26 and similarly the wall 23 is adapted to become spaced from the auxiliary wall 21 when the walls 'of the tray are folded into erected position. At

the same time the flanges 24 and 25 are caused to extend outwardly from the walls 22 and 23 and at right angles thereto. The arrangement of the parts, when the carton is erected, is best shown in Fig. 9.

The hoop B as stated is best shown in Fig. 7 and is constructed from a strip of cardboard or other suitable material of a width equal to the height of the lateral walls of the tray A. This strip is scored at the four corners, as indicated at 31, 38, 39 and 4|, to form lateral walls 22a, 23a, 31a and 32a and a fiap 42 connected with the wall 22a. The flap 42 is adapted to be secured to the end wall 3la by adhesive or otherwise and ties the end of the hoop B together. The hoop B is adapted to be applied over the walls of the tray A or stating it differently said tray is adapted to be received within the said hoop and to telescope with reference thereto. Inasmuch as the Walls of tray A are disconnected at their adjoining edges, the hoop B holds the walls from spreading and maintains the tray in erected form.

The cover C is constructed from a blank of paper cardboard or some similar paper product which is best shown in Figs. 2 and 3. This blank is formed with longitudinal scores 43 and 44 and with transverse scores 45 and 46 which divide the blank into a top 41, end walls 3|b and 32b, and side walls 22b and 23b. In addition, the blank is cutalong the scores 44 and the end walls 3Ia and 32a. The scores 31, 38 39 and 4| do not extend across these tongues so that, when the structure is folded the tongues remain in the planes of the end walls 3la and 32a and extend outwardly from the side walls 221: and 23a, as shown in Fig. 7. For cooperation with these tongues, a number of slots 54 are cut in the side walls 22b and 23b of the cover C. When the hoop B is inserted into the cover C, tongues 53 engage said slots and hold the hoop secured to the cover.

. The manner of using the invention is as follows: The cheese or other substance to be packaged in the package is usually wrapped in paper, tin foil or some other suitable wrapping material. For this purpose a sheet of such material is placed upon the tray A when the same is collapsed. By means of suitable machinery, now available for the purpose, the sheet is folded to form a container open at the top, the excess portions of the sheet being doubled back upon themselves and overlapping at the ends of the container. This construction and method of wrapping such commodities being well known in the art, has not been shown in this application. The lateral walls of the tray A are folded s cheese into the same until the required amount 43 up to the scores 45 and 46 to form fiaps 48 which are folded back; and secured to the end walls 3 lb and 32b by means of adhesive or otherwise. The side walls 22b and 23b of the cover 0 are formed with diagonal scores 49 which permit of collapsing the carton so that the same may take the form shown in Fig. 2.

The cover C is constructed at the lower portions of the side walls 22b and 23b thereof, with finger notches 5!. In like manner the hoop B is constructed with similar finger notches 52 which, when the parts are assembled, are adapted to register with one another. These finger notches permit of grasping the tray A at the lowermost portion thereof and by holding the cover C of removing the tray from the cover.

The hoop B is held attached to the cover C by means of a number of locking tongues 53. These tongues are struck out of the material formin the side walls 22a and 23a and are integral with of cheese has been poured. The expanded portion of the wrapper or container is then folded over upon the melted cheese and the cover C applied to the entire assembled structure. The cheese is now properly packaged. Due to the flanges 24 and 25, the side walls of the tray B are greatly reinforced and bowing of these walls due to the pressure of the molten cheese is resisted. As the cover C is applied to the assembled structure, the tongues 53 are forced into the slots 54 and the lower edges 55 of said slots which form shoulders engage corresponding shoulders 56 on the said tongues and hold the hoop secured to the cover C. Whenever it becomes desirable to remove the contents of the package, for the purpose of dispensing the contents, the finger and thumb may be placed in the finger notches 5| and 52 and the lowermost portion of the tray A readily grasped. This tray may now be removed from the cover. Due to the fact that the hoop B is locked with reference to the cover C the hoop remains in the cover and the tray and contents are separately withdrawn from the hoop and cover. Upon being fully removed, the lateral walls of the tray A are free and may be swung outwardly into collapsed position, as shown in Fig. 4. When so swung, the solidified cheese is exposed and the wrapper or container enveloping the same may be easilyremoved and access had to the cheese. While the parts are so disposed the bottom 2| of the tray A forms a cutting board on which the cheese may be cut. Where a part only of the cheese is used the walls of the tray may be folded into erected position and the cover with the hoop attached which serve as a closure for the carton again applied to the tray to close the same. If desired, the lateral walls of the tray may be broken away at the scores forming the hinges between the same and the bottom of the tray to facilitate application of the cover thereto. We have found that, where the end walls only are broken away, the side walls may be readily held in erected position while the cover is being applied to the tray. In'suoh case the ends of the side walls hold the tray from longitudinal movement relative to the cover.

In the drawings it will be noted that the end walls 3| and 32 of the tray A are slightly wider than the bottom 2|, between the scores I5 and Hi. This is for the purpose of causing the said end walls to abut up against the end walls 22 and 23 and the auxiliary walls 26 and 21 of the tray when the same are erected. This prevents the end walls from unintentionally folding into th interior of the tray while the cheese is being poured into the container or wrapper. We have found that, due to the pairs of scores l2l5 and Iii-49, no tendency of the side walls to toe inwardly will result. fore, when the end walls abut against the side walls, the hoop holds all of the parts in position and the parts so remain while the cheese is being poured.

In the explanation of our invention we have shown the flanges and 25 issuing from the upper edges of the side walls of the tray. It can readily be comprehended that similar flanges may also be used on the end walls, if desired. Also the flanges, instead of being formed on the walls of the tray might equally as well be formed on the walls of the hoop. Similarly the auxiliary walls used with the flanges might be formed on the walls of the hoop, as well as on the walls of the tray.

While we have described the locking tongues for holding the hoop attached to the cover, it can readily be understood that glue may be applied to the hoop or cover as the parts are assembled which would cause the same to stick together and'prevent removal of the hoop when the cover is removed from the tray.

-Our invention is hghlv advantageous in that an extremely simple and practical construction is provided whereby the cost of packaging cheese may be reduced. At the same time a greatly convenient, construction is provided in which the cheese may be directly placed in the ultimate container Without requiring the additional handling necessary where the cheese is first poured in suitable molds and subsequently packaged. With our invention the carton in which the cheese is packaged is readily opened by the user and when open the walls of the tray are easily disassembled to give access to the contents of the'tray, W th our invention the hoop is held attached to the cover so that, after the same has served its purpose, namely, to hold the tray in erected position while the cheese is being poured, the said hoop is out of the way and does not interfere with the dispensing of the cheese or other substance within the carton.

Changes in the specific form of our invention, as herein disclosed, may be made within the scope of what is claimed without departing from the spirit of our invention.
